Title: Inventor Spotlight: Richard M. Harrington

Introduction

Richard M. Harrington, a distinguished inventor based in Cincinnati, OH, has made significant contributions to the field of foam pattern techniques. With a total of three patents to his name, he stands out as a key figure in innovative casting methods that cater to the investment casting industry.

Latest Patents

His latest patents feature groundbreaking techniques for creating fugitive foam patterns used in investment casting operations. In one illustrative embodiment, Harrington's method involves assembling a fugitive foam pattern from independently formed sections. The process starts with forming a first section in a mold, which is then cured before connecting it to a second section through a mating surface that adheres integrally. Additionally, alternative embodiments include creating channels within foam patterns using a temporary core made from water-soluble or acid-soluble materials that can be removed without chemical leaching. This innovation allows for more intricate designs and improved efficiency in manufacturing processes.

Another recent patent presents a method where a liquid mixture, created by combining a polyol component and an isocyanate component, is used to generate a foam pattern. This process involves placing a temporary core into a mold, surrounding it with the liquid mixture, and allowing it to react and form a structural foam pattern. Remarkably, the method also incorporates the use of foam supporting pins that become integral to the final pattern, simplifying subsequent processing and enhancing the overall design.

Career Highlights

Harrington's impressive career includes significant roles at Ic Patterns, LLC, and Fopat LLC, where he honed his skills in developing innovative casting techniques. His work in these companies allowed him to explore and advance the potential applications of foam materials in industrial settings.
